The impostor phenomenon is considered in relation to origins in interp
ersonal and social contexts. Specifically, messages given in the famil
y and in society via gender-role socialization are examined as catalys
ts for impostor feelings. Impostor feelings in relation to success and
social mobility in women also are addressed. Given this interpersonal
/social context, the authors suggest that the most efficacious treatme
nt modality for the impostor phenomenon is a feminist-oriented women's
group. The phases of women's impostor groups are outlined and general
group issues are noted.
